Penguin sound for house party :)

Hey guys,

we are trying to set up a sound system for a party in several rooms. Asthey are directly next to each other, simultaneous playback of soundinside the two rooms would be really great.Now I know that Apples AirPlay made it possible to stream sound to severaldevices and play it back in sync - but neither of us owns an Apple device.

Before borrowing some Apple stuff, we're of course eager to try it on Linux ;-)Our setup consists of two machines: a headless device that is supposedto receive only and my desktop where the music should be chosen.Both machines are connected to speaker systems of their own and run Arch Linux.And they are also in the same network. So to sum it up:

2 machines, both Archlinux

same network

both should play back sound simultaneously

sound is streamed from one machine

Now, I have experimented a little with local HTTP-sound streaming a little butthat was more than a little fiddling and always went out of sync after a little while.Ideally, what I'd love to have, is a system that you could hook on to alsa,so that everything that is played back on the one device arrives at the other and is alsoplayed back in sync.

Now, is there such a thing?I have found shairplay, and several RTP experiments but not a single solutionreally fits my needs. Am I looking for the wrong thing, or are our requirements simply utopian?I would be really really great, if someone could help us out!
